Supplemental Terms or Conditions

Party B’s Designated Offices: Philadelphia

Pursuant to the terms of paragraph 1 of the Agreement, Buyer and Seller agree to be governed by the Supplemental Terms and Conditions stated herein. To the extent that any provisions in these Supplemental Terms and Conditions are in conflict with provisions contained in the Agreement, the provisions contained in these Supplemental Terms and Conditions shall prevail.

Notwithstanding anything herein to the contrary, this Agreement shall amend and restate the Global Master Repurchase Agreement, dated as of July 21, 2011, between Party A and Party B (the “Initial Agreement”), and any obligations, liabilities or rights of the parties under the Initial Agreement shall be deemed to be assumed and incorporated herein, subject to the revised terms of this Agreement.

(ii) Party B represents that it is a limited liability company organized under the laws of Delaware that is disregarded as an entity separate from its owner, FS Investment Corporation, for United States federal income tax purposes.

Notwithstanding anything to the contrary in this Agreement, in the case of a transfer by Party A of its rights and obligations under this Agreement, Party B shall not be

7

required to pay additional amounts to any person in excess of the additional amounts it would have been required to pay to Party A if no such transfer had occurred.

The following shall constitute Additional Events of Default with respect to which Party B will be the Defaulting Party and shall be inserted following Section 10(a)(x) of the Agreement:

8

With respect to Party A, only the events enumerated in paragraph 10(a)(i) through 10(a)(vi) shall constitute Events of Default and, in the case of paragraphs 10(a)(i) through (v) only if: (x) such event remains uncured at the end of the third Business Day following the date on which notice of such failure has been delivered to Party A and (y) is not excused by illegality, impossibility or force majeure.

As specified in the Agreement and for the avoidance of doubt, it is the intent of the parties hereto that all cash amounts payable in the same currency on the same day hereunder, whether as Income, cash proceeds of redemption of Purchased Securities included in the definition of Equivalent Securities, Purchase Price, Repurchase Price, Cash Margin or otherwise, should be netted off, and thus, if on any date amounts would otherwise be payable in the same currency by each party to the other, then, on such date, each party’s obligation to make payment of any such amount will be automatically satisfied and discharged and, if the aggregate amount that would otherwise be payable by one party exceeds the aggregate amount that would otherwise be payable by the other party, replaced by an obligation of the party with the larger aggregate amount payable to pay the other party the excess of the larger aggregate amount over the smaller aggregate amount.

It is the intent of the parties that if one Repurchase Transaction is maturing and another Repurchase Transaction with respect to the same Purchased Securities is commencing on the same day, the Buyer is authorised to retain the Purchased Securities for the maturing Transaction to the extent necessary to satisfy the obligation of the Seller to deliver Purchased Securities in respect of the new Transaction.

The parties agree to treat all Transactions under this Agreement as loans from Party A to FS Investment Corporation for federal, state and local income and franchise tax purposes.

On the date hereof and each day this Agreement or any Transaction under this Agreement is still outstanding, Party B represents, warrants and covenants as follows:

9

(i) any litigation, investigation, regulatory action or proceeding that is pending or threatened by or against Party B in any federal or state court or before any governmental authority which, if not cured or if adversely determined, would reasonably be expected to have a material adverse effect on Party A’s rights hereunder or constitute an Event of Default under this Agreement; and

(ii) promptly upon receipt of notice or knowledge of any lien or security interest (other than Permitted Liens) on, or claim asserted against, any of the Purchased Securities, the Custodial Account (as defined below) or any Collateral (collectively, the Purchased Securities, Custodial Account and the Collateral, the “Protected Items”).

For the avoidance of doubt, the notice requirements contained in Paragraph 10(l) shall apply to all Events of Default contained in this Annex I.

11

(i) distributions to any Member (as defined in the LLC Agreement) of Party B in cash or Collateral Assets where such distribution is payable solely from (x) income or dividends received by Party B on the Collateral, (y) monies representing capital appreciation received with respect to Collateral that has matured or has been transferred pursuant to this Agreement, or (z) any Collateral, regardless of the applicability of clause (x) or (y), if after such distribution the Adjusted Net Worth of the Collateral would be at least equal to $720,000,000) (except that (i) for a period from 60 days after the date hereof, such limit shall be $678,000,000 and (ii) for a period from and after 60 days after the date hereof until the Amendment Effective Date, such limit shall be $814,000,000); provided, Party B is prohibited from making any distribution in accordance with this subclause (i) unless immediately prior to and immediately after giving effect to such distribution the Adjusted Net Worth of the Collateral will be greater than the Collateral Minimum;

12

(ii) payments to purchase Collateral Assets meeting the Investment Guidelines and the terms of Section 8(b) of this Annex I; provided, Party B is prohibited from making any purchase in accordance with this subclause (ii) unless immediately prior to and immediately after giving effect to such purchase the Adjusted Net Worth of the Collateral will be greater than the Collateral Minimum;

(iii) payments of (1) operating expenses and governmental and regulatory fees, and (2) fees, expenses and indemnities payable under the LLC Agreement or the Collateral Management Agreement; provided, Party B is prohibited from making any distribution in accordance with this subclause (iii)(2) unless immediately prior to and immediately after giving effect to such distribution the Adjusted Net Worth of the Collateral will be greater than the Collateral Minimum; and

(iv) payments of the purchase price for any assets sold to Party B by FS Investment Corporation pursuant to the Asset Transfer Agreement (such assets, “Sold Assets”) by transferring Collateral Assets then owned by Party B to FS Investment Corporation having a Fair Market Value at the time of such transfer equal to the Fair Market Value of the Sold Asset transferred to Party B as of the date of acquisition of such Sold Asset (such value, the “Initial Fair Market Value”); provided, however, that in the case of Collateral Assets that previously were sold to Party B by FS Investment Corporation (each, a “Prior Sold Asset”), the Initial Fair Market Value of such Prior Sold Asset to be transferred to FS Investment Corporation as part of the purchase price, when aggregated with the Initial Fair Market Value of all other Prior Sold Assets previously transferred to FS Investment Corporation as part of the purchase price of Sold Assets, is less than or equal to 10% of the aggregate Initial Fair Market Value as of the respective date of acquisition of all Prior Sold Assets at any time hereunder.

For the avoidance of doubt, any breach of these representations shall be considered an Event of Default under Paragraph 10(a)(vii) of the Agreement.
